How to Reset Your LG Smart Inverter Refrigerator

When and Why to Reset Your LG Smart Inverter Refrigerator

A reset clears temporary settings and error codes without erasing your saved preferences or food safety settings. You should reset your LG Smart Inverter refrigerator if the display is frozen, the ice maker stops working, temperature controls are not responding, or the compressor runs constantly without cooling properly. A reset also fixes most connection problems with the LG ThinQ app.

The reset process takes about 5 to 10 minutes and requires no tools. Your food stays cold throughout—the compressor keeps running, and your saved temperature settings remain in place. A reset is different from a factory reset, which erases all custom settings and should only be done if you are troubleshooting a serious malfunction or preparing the unit for donation or resale.

Key Takeaways

• A soft reset clears error codes and freezes without erasing your temperature settings or saved preferences.
• Unplug the refrigerator for 10 minutes, then plug it back in—this is the safest and most effective reset method.
• If unplugging does not work, use the control panel reset: hold the Ice Plus and Refrigerator buttons together for 3 to 5 seconds until the display blinks.
• Wait 24 hours after a reset before judging whether the problem is fixed, because the compressor needs time to stabilize.
• If the refrigerator still does not cool or the display remains blank after a reset, the issue is likely a hardware failure that requires service.

The Safest Reset Method: Unplugging

Unplugging the refrigerator is the gentlest way to reset it and works for most problems. Locate the power cord at the back of the unit or the outlet it plugs into. Unplug the refrigerator completely—do not use the power button on the control panel, because that does not fully disconnect the electronics.

Leave it unplugged for a full 10 minutes. This gives the control board time to discharge and clears any temporary errors stored in memory. After 10 minutes, plug the refrigerator back in. The display will light up, and the compressor will restart. You will hear a brief humming sound as the system powers up—this is normal.

Check the display to confirm it is responding. If the temperature readings appear and the buttons light up when you touch them, the reset worked. The refrigerator will take 2 to 4 hours to return to your set temperature, so do not open the doors more than necessary during this time.

Control Panel Reset for Frozen or Unresponsive Displays

If the display is frozen or the buttons do not respond, try a control panel reset before unplugging. On most LG Smart Inverter models, the reset buttons are Ice Plus and Refrigerator—both located on the front control panel. Check your model's manual or the inside of the refrigerator door for the exact button locations, because some models use different labels.

Press and hold both buttons at the same time for 3 to 5 seconds. You will see the display blink or flash, and you may hear a beep. Release the buttons immediately. The display will go dark for a few seconds, then light up again with the default settings showing. This reset clears the control board without powering down the compressor.

If the display remains blank or unresponsive after holding the buttons, the control panel itself may be faulty. In that case, proceed to the unplugging method as a backup. If both methods fail to restore the display, the control board likely needs replacement by a service technician.

Resetting the Ice Maker Specifically

If only the ice maker is not working but the refrigerator is cooling normally, you can reset just the ice maker without affecting other settings. Locate the Ice Plus button on the control panel and press it once. This button toggles ice production on and off and also resets the ice maker cycle.

When you press Ice Plus, the display will show an indicator (usually an ice cube icon or the words "Ice Plus") lighting up. The ice maker will begin a test cycle, which takes about 6 to 24 hours to produce the first batch of ice. Do not open the ice bucket or dispenser during this time.

If ice still does not appear after 24 hours, check that the water line is connected and the inlet valve is not frozen. A full unplugging reset may also help if the ice maker's control circuit is stuck. If ice production still does not resume, the inlet valve or ice maker assembly may need service.

What to Do If the Reset Does Not Work

Wait at least 24 hours before deciding the reset failed. The compressor and temperature sensors need time to stabilize after a power cycle, and some error codes take a full day to clear. During this time, keep the doors closed as much as possible and avoid adjusting the temperature settings.

After 24 hours, check the display for error codes. Common codes include 1F or FF (freezer sensor failure), dE or dH (door seal problem), or IE (water inlet issue). Write down any code you see. These codes tell a service technician exactly what is wrong and speed up repairs.

If the refrigerator is still not cooling, the compressor is running constantly, or the display remains blank, the problem is likely a failed component—not a software glitch. Contact LG customer service or a certified repair technician. Provide them with the model number (found on the back or inside the door frame) and any error codes. Do not attempt further resets, because repeated power cycles can damage the control board.

Resetting the ThinQ App Connection

If your LG Smart Inverter refrigerator is not connecting to the ThinQ app or the app shows "offline," reset the Wi-Fi connection without resetting the entire refrigerator. Open the ThinQ app on your phone and go to Devices. Select your refrigerator, then tap Settings or the gear icon. Choose Remove Device or Disconnect.

On the refrigerator's control panel, hold the Wi-Fi button (if your model has one) for 3 seconds until the Wi-Fi icon blinks. This clears the stored network information. Then open the ThinQ app again, tap Add Device, and follow the on-screen steps to reconnect. Make sure your phone and refrigerator are on the same Wi-Fi network, and that your network password is correct.

If the refrigerator still will not connect after this reset, the Wi-Fi module may be faulty. Restart your router by unplugging it for 30 seconds, then plug it back in. If other devices connect normally but the refrigerator does not, contact LG support—the Wi-Fi card may need replacement.

Avoiding Common Reset Mistakes

Do not flip the circuit breaker to reset the refrigerator. A circuit breaker cuts power suddenly and can damage the control board. Always unplug the unit directly or use the power outlet. Do not hold the reset buttons for longer than 5 seconds—holding them too long can trigger a factory reset, which erases all your custom settings and temperature preferences.

Do not reset the refrigerator more than twice in a row. If two resets do not fix the problem, the issue is hardware-related, and further resets will not help. Repeated power cycles can actually shorten the lifespan of the control board. Instead, document the problem and contact a service technician.

Do not open the doors or adjust settings during the first 2 hours after a reset. The compressor is recalibrating, and interference can cause it to cycle incorrectly. If you need to access food, do so quickly and close the door immediately. Temperature will stabilize faster if you leave the unit alone.

Frequently Asked Questions

Will a reset make my refrigerator lose its temperature settings?

A soft reset (unplugging or pressing control panel buttons) keeps your saved temperature settings. A factory reset erases them. If you are doing a soft reset, your preferences stay in place. If you accidentally trigger a factory reset, the refrigerator will return to default temperatures (usually 37°F for the fridge and 0°F for the freezer), and you will need to adjust them again.

How long should I wait before plugging the refrigerator back in?

Wait a full 10 minutes. This gives the capacitors on the control board time to fully discharge. Plugging it back in too soon (after 1 or 2 minutes) may not clear the error, and you will have to unplug it again. Set a timer on your phone to make sure you wait the full time.

What if the refrigerator beeps constantly after a reset?

Constant beeping usually means a door is not closing properly or a sensor is blocked. Check that both the refrigerator and freezer doors are fully shut and the seals are clean. If the beeping continues after closing the doors, unplug the unit for 10 minutes again. If it still beeps after the second reset, the door sensor may be faulty and need service.

Can I reset the refrigerator while food is inside?

Yes. The compressor keeps running during a reset, so food stays cold. You do not need to remove anything. Just avoid opening the doors during the reset process, because that lets cold air escape and slows the stabilization process.

What is the difference between a soft reset and a factory reset?

A soft reset clears error codes and temporary glitches but keeps your temperature settings and preferences. A factory reset erases everything and returns the refrigerator to its original factory state. You should only do a factory reset if a service technician tells you to, or if you are preparing the unit for donation or resale.
